Even so, I still have a problem. When the example is run on OS X intel, the only signal code supplied to the handler in the si_code field of the siginfo_t structure, when it's invoked on SIGFPE, is FPE_NOOP. OS X ppc and GNU/Linux both supply at least FPE_FLTDIV and FPE_FLTINV -- other codes not tested yet. [...]

So am I doing something wrong?

Nobody seems to have an idea about this? :-( After experimenting with more cases, AFAICT I'm not doing anything wrong -- the discrepancy is real.

So let me advocate that the discrepancy be resolved to make the intel behavior for sigaction() the same as that for ppc and GNU/Linux. [...]

Am I off base here?

You aren't running Snow Leopard, where this is fixed, are you? No, I'm running 10.5.8, Leopard. (Actually I did say that before...) That's good news! Thanks for letting me know! -- David
